As shown in Figure 1, a seed pelletizing coating machine under the action of a vibrating force field comprises a frame on which a powder hopper 1, a seed hopper 18, a weighing system 3, a powder delivery pipe 5, Liquid medicine pipeline 6, liquid medicine storage tank 7, high-pressure pump 8, high-pressure pump motor 9, rotary stepper motor 10, coating pot motor 11, coated seed outlet 12, vibrator 13, coating pot 14, nozzle 15 , seed splitter plate 16 and controller 17.

The powder hopper 1 and the seed hopper 18 are located above the frame, and the outlets of the powder hopper 1 and the seed hopper 18 are provided with regulating valves 2, and the outlets of the powder hopper 1 and the seed hopper 18 are connected to the weighing system 3 ; The weighing system 3 is a screw scale, and the screw scale is driven by a stepper motor 4 .

The outlet of the weighing system 3 below the powder hopper 1 is connected to the powder delivery pipe 5 , and the other end of the powder delivery pipe 5 is inserted into the inside of the coating pan 14 . The outlet of the weighing system 3 below the seed hopper 18 is provided with a seed splitter plate 16 .

The liquid medicine storage tank 7 is connected to the high-pressure pump 8 and connected to the spray head 15 through the liquid medicine pipeline 6, and the spray head 15 is located below the seed distribution plate 16.

The coating pot 14 is connected to the coating pot motor 11 through the coating pot motor shaft, and the vibrator 13 is fixedly arranged on the coating pot motor shaft; in order to better vibrate to improve the coating rate, the vibrator 13 can carry out horizontal direction and electric vibrator vibrating in the vertical direction.

The rotary stepper motor 10 is used to drive the coating pan 14, the main shaft of the coating pan motor, the vibrator 13 and the coating pan motor 11 to rotate together in a circumferential direction.

The rotary stepper motor 10 drives the coating pan 14 to rotate circumferentially through the worm and gear, so that in the coating process, the feed inlet of the coating pan 14 faces the seed splitter plate 16; The feed opening is towards the coated seed outlet 12 .

Controller 17 is connected with weighing system 3 , regulating valve 2 , high-pressure pump 8 , vibrator 13 , coating pan motor 11 , and rotary stepper motor 10 . In order to realize quantitative feeding, quantitative liquid supply, automatic collection and processing of sensor signals and automatic adjustment of powder and liquid supply, etc., it has a high degree of automation.

The seeds and powder are fed into the seed hopper 18 and the powder hopper 1 respectively through the hoist, and the feeding amount is adjusted to the required amount by adjusting the regulating valve 2 according to different seeds, so as to realize quantitative feeding, and the seeds pass through the weighing system 3 to carry out Weighing, accurate cutting. At the same time, the medicinal liquid is mixed according to the requirements of different seeds according to a certain ratio and stored in the medicinal liquid storage tank 7, and is pumped to the nozzle 15 by the high-pressure pump 8 under the drive of the high-pressure pump motor 9 for atomization. At this time, the seeds pass through the seed distribution plate 16 The flow is split into a single curtain, and the seeds are in contact with the atomized liquid medicine during the falling process, so that the liquid medicine forms a film on the surface of the seeds. Then, the seeds wrapped with the medicament enter the coating pan 14, and the powder is weighed and fed according to the amount of the seeds, and the powder is delivered to the coating pan 14 through the pneumatic powder delivery pipe 5, and mixed with the seeds. The coating pot 14 starts to rotate under the drive of the coating pot motor 11. At this time, the vibrator 13 vibrates according to the requirements of different seeds. Under the vibration of the vibrating force field, the powder is more evenly and firmly adhered. On the surface of the seeds, it can effectively increase the coating rate of the seeds, especially the single-seed rate of pelleting, the compressive strength of single-seed and the near-roundness of pelleting. According to the requirements of different seeds, it is necessary to perform coating pelletization several times. After one coating is completed, the adhesive needs to be sprayed on the surface of the seeds again, and then the powder is sprayed into the coating pot again, and the first process is repeated until the seeds are reached. Coating pelletization requirements. After pelleting, the coating pot 14 is rotated by rotating the stepper motor 10, the pelletized seeds are poured into the coated seed outlet 12, and the pelletized seeds are discharged from the coated seed outlet 12, and the whole process is completed .
